Through a time-series of user experience(UX), multiple senses, such as vision, hearing, and touch, interact with a product. Cross-modal studies have shown that multiple senses interact each other and change their perceptions. In this paper, we propose a Kansei modeling methodology by considering multisensory interactions of UX. In this methodology, we structure the user’s Kansei as a cognitive process involving four layers: physical quantity, perceived features, delight factor, and delightful experience. We extract the layered structure for each scene of the user experience. Each scene consists of the user’s senses and action. With our modeling methodology, we extract cognitive components involving multimodal integration from comprehensive cognitive structures of the UX. Based on expectation theory as a principle of contextual cross-modal interactions, we identify the tolerance of a perceived feature that satisfies multiple delight factors, involving attractive and must-be qualities in the Kano model. We demonstrate the validity of the methodology with an experiment using of a hair dryer multisensory design.
